Digital indicator M3 Frequency tricolour

Tricolour digital indicator for frequency measuring.

Item description

The M3-3FT5B.0307.W70BD is a tricolour 5-digit meter for pulse measuring via incremental encoder, NPN/PNP- or Namur-sensor and a visual limit value monitoring via the display. Configuration happens via three front keys or via an optional PC-software. Optional one analog output, one frequency output, interfaces RS232/RS485 and two switching points are available. Selectable software functions and a direct limit value ad- justment in operating mode complete the modern device concept.
